The semiconductor package 10 may be, for example, a chip-on-film (COF) semiconductor package.

The semiconductor chip 100 may be disposed in a circuit region of the base film 110, in particular, a chip mounting region. The semiconductor chip 100 may be a driving chip used to drive an apparatus. When the semiconductor package 10 is coupled to, for example, a display apparatus, the semiconductor chip 100 may be a display driving chip used to drive the display apparatus. In example embodiments, the semiconductor chip 100 may be a source driving chip generating an image signal using a data signal transmitted from a timing controller and outputting the image signal to a display panel. In other embodiments, the semiconductor chip 100 may be a gate driving chip outputting a scan signal including an ON/OFF signal of a transistor to the display panel. However, the type of the semiconductor chip 100 is not limited thereto. When the semiconductor package 10 is coupled to an apparatus other than the display apparatus, the semiconductor chip 100 may be a chip for driving the corresponding electronic apparatus.

FIGS. 1 to 3 illustrate an embodiment in which the semiconductor package 10 includes one semiconductor chip 100, but the number of semiconductor chips 100 is not limited thereto. In some embodiments, the semiconductor package 10 may include two or more semiconductor chips.

The semiconductor chip 100 may include a substrate. The substrate is a semiconductor substrate and may have an active surface and an inactive surface opposite each other. In example embodiments, the substrate may be a silicon (Si) wafer including crystalline silicon, polycrystalline silicon, or amorphous silicon. In other embodiments, the substrate may include or may be formed of a semiconductor element, such as germanium (Ge), or a compound semiconductor, such as silicon carbide (SiC), gallium arsenide (GaAs), indium arsenide (InAs), and indium phosphide (InP).

The base film 110 may be a flexible film. The base film 110 may be an insulating film. In example embodiments, the base film 110 may include or may be formed of resins, such as polyimide (PI), polyamide (AD), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulphone (PES), polyacrylate (PAR), polyetherimide (PEI), polyphenylene sulfide (PPS), polyallylate, polycarbonate (PC), cellulose triacetate (TAC), and cellulose acetate propionate (CAP).

The base film 110 may include a first surface S1 on which the semiconductor chip 100 is mounted and a second surface S2 opposite to the first surface S1.

The conductive structure 120 may include a first conductive structure 123 disposed on the first surface S1 of the base film 110, a second conductive structure 126 disposed on the second surface S2 of the base film 110, and a via 129 passing through the base film 110.

Referring to FIGS. 1 and 3 , the first conductive structure 123 may include first conductive lines 123L and first conductive patterns 123G connected to the first conductive lines 123L. The first conductive lines 123L may be leads electrically connecting the semiconductor chip 100 to the pads 160. For example, one end portions of the first conductive lines 123L may be connected to the semiconductor chip 100, and other end portions of the first conductive lines 123L may be connected to the pads 160. One end portions of the first conductive lines 123L may be connected to bumps BS disposed below the semiconductor chip 100, respectively. The other end portions of the first conductive lines 123L may correspond to the pads 160, respectively, and may be electrically connected thereto. In some embodiments, the semiconductor chip 100 may include the bumps BS.

The first conductive patterns 123G may extend from the first conductive lines 123L. The first conductive patterns 123G may have, for example, a larger width or a larger region than that of the first conductive lines 123L. In FIG. 1 , the first conductive patterns 123G are illustrated as having a circular or oval shape, but the shapes of the first conductive patterns 123G are not limited thereto. Also, although FIG. 1 illustrates that the semiconductor package 10 has two first conductive patterns 123G for convenience of description, the present inventive concept is not limited thereto. The semiconductor package 10 may include a single or three or more first conductive patterns 123G. In some embodiments, the first conductive lines 123L may include conductive lines connected to the first conductive patterns 123G, respectively, and conductive lines that are not connected to the first conductive patterns 123G. In some embodiments, the conductive lines connected to the first conductive patterns 123G may include at least one conductive line connected to a ground pad 160G and at least one conductive line connected to a power pad 160P. When viewed in a plan view, each of the first conductive patterns 123G may be spaced apart from or may overlap a corresponding first conductive line among the first conductive lines 123L. A first conductive pattern 123G that is spaced apart from a corresponding first conductive line may be connected to the corresponding first conductive using an auxiliary conductive line 123L-A.

The first conductive lines 123L electrically connected to the first conductive patterns 123G may be connected to the ground pad 160G or the power pad 160P of the pads 160. The first conductive patterns 123G electrically connected to the ground pad 160G or the power pad 160P may be exposed through first openings 133OP1 of the first insulating layer 133 to contact the first capping layer 153. In some embodiments, each of the first conductive patterns 123G may be exposed by a corresponding first opening of the first openings 133OP1, and may have a larger width or a larger region than that of the corresponding first opening. In some embodiments, the first capping layer 153 may be connected to the first conductive lines 123L that are electrically connected to the ground pad 160G or the power pad 160P via the first conductive patterns 123G. The first conductive patterns 123G that have larger areas than corresponding first conductive lines may facilitate connection between the first capping layer 153 and the corresponding first conductive lines. The term “contact,” as used herein, refers to a direct connection (i.e., touching) unless the context indicates otherwise.

Referring to FIGS. 2 and 3 , the second conductive structure 126 may be a plate-shaped conductive pattern covering the second surface S2 of the base film 110. The second conductive structure 126 may be electrically connected to the first conductive patterns 123G of the first conductive structure 123 through the via 129 passing through the base film 110. One surface of the second conductive structure 126 may contact the second surface S2 of the base film 110, and the other surface of the second conductive structure 126 may contact the second capping layer 156. In example embodiments, the second conductive structure 126 may not include a wiring transmitting a signal.

The bumps BS of the semiconductor package 10 may connect the semiconductor chip 100 to the first conductive lines 123L of the first conductive structure 123. The semiconductor chip 100 may be mounted on the base film 110 through a flip chip bonding process. The bumps BS may include or may be, for example, solder balls provided on an active surface of the semiconductor chip 100. The bumps BS may be provided on the active surface of the semiconductor chip 100 to be physically and electrically coupled to the first conductive lines 123L on the base film 110.

The bumps BS may include conductive bumps serving as input terminals, and conductive bumps serving as output terminals. Through the bumps BS, the semiconductor chip 100 may receive at least one of a control signal, a power signal, and a ground signal for an operation of the semiconductor chip 100 from the outside through the bumps BS, may receive a data signal to be stored in the semiconductor chip 100 from the outside, or may provide data stored in the semiconductor chip 100 to the outside.

The first insulating layer 133 may be disposed on the first surface S1 of the base film 110. The first insulating layer 133 may prevent an unintended connection between the first conductive structures 123 and may protect the first conductive structures 123 from external physical and/or chemical damage.

The first insulating layer 133 may include a plurality of openings 133OP1 and 133OP2. A portion of the openings 133OP1 may expose the first conductive patterns 123G, and a portion of the openings 133OP2 may expose a region in which the semiconductor chip 100 is mounted, thereby exposing end portions of the first conductive lines 123L. The first insulating layer 133 may cover the first conductive structure 123 in a region excluding the first conductive patterns 123G connected to the semiconductor chip 100 and a mounting region of the semiconductor chip 100.

The first capping layer 153 and the second capping layer 156 may be disposed on the first surface S1 and the second surface S2 of the base film 110, respectively. The first capping layer 153 may cover the first insulating layer 133 and may contact the first conductive patterns 123G exposed by the opening 133OP1 of the first insulating layer 133. The first capping layer 153 may cap the semiconductor chip 100. Referring to FIG. 3 , the first capping layer 153 may include a first portion 153 a contacting the first conductive patterns 123G and the first insulating layer 133 on the first surface S1 of the base film 110, a second portion 153 b disposed on an upper surface of the semiconductor chip 100, and a third portion 153 c disposed between the first portion 153 a and the second portion 153 b. In some embodiments, the third portion 153 c may connect the first portion 153 a to the second portion 153 b. The third portion 153 c may be spaced apart from the side surface of the semiconductor chip 100 and may have an oblique shape. However, the shape of the first capping layer 153 is not limited thereto.

The second capping layer 156 may be disposed on the second surface S2 of the base film 110 to cover a lower surface of the second conductive structure 126. In example embodiments, the second capping layer 156 may cover the entire lower surface of the second conductive structure 126 and cover a side surface of the second conductive structure 126. The second capping layer 156 may have a width greater than a width of the second conductive structure 126 in an X-direction and a Y-direction.

The first capping layer 153 and the second capping layer 156 may be formed of a rigid material having conductivity. In some embodiments, each of the first capping layer 153 and the second capping layer 156 may include or may be a conductive layer including metal. The first capping layer 153 and the second capping layer 156 may include or may be formed of, for example, copper (Cu), aluminum (Al), silver (Ag), gold (Au), nickel (Ni), tin (Sn), or zinc (Zn), chromium (Cr), manganese (Mn), indium (Id), palladium (Pd), titanium (Ti), molybdenum (Mo), or platinum (Pt). In example embodiments, the first capping layer 153 and the second capping layer 156 may be formed of at least one of aluminum (Al) and copper (Cu).

The semiconductor package 10 may include a first capping layer 153 (i.e., a first conductive layer) and a second capping layer 156 (i.e., a second conductive layer) on opposite surfaces of the base film 110, respectively, so that electrical characteristics and heat dissipation characteristics may be improved. For example, the first and second capping layers 153 and 156 may be in contact with the first and second conductive structures 123 and 126, respectively, and the wiring lines electrically connected to the first and second capping layers 153 and 156 may be electrically connected to the ground pad 160G or the power pad 160P. By electrically connecting the first and second capping layers 153 and 156 formed of a conductive material to the ground pad 160G or the power pad 160P, EMI may be shielded on opposite surfaces of the base film 110. When the second conductive structure 126 is electrically connected to the ground pad 160G, electrostatic discharge (ESD) characteristics may be improved due to a contact region between the second conductive structure 126 and the second capping layer 156, and a return path may be secured to improve signal integrity (SI). At the same time, the first and second capping layers 153 and 156 may absorb and release heat generated by the semiconductor chip 100, and the like, so that the heat dissipation characteristics of the semiconductor package 10 may be improved. In some embodiments, the ground pad 160G may include at least one ground pad, and the power pad 160P may include at least one power pad.
